' 107mm may concern e if known that l, M "THIAS Bacon, of the United residing at 11 in the county of Suffolk and State r w Y g! f T 5 or nrcsichusetts V8 ll'l'wciltfiti certain imin Shapingdachines for Shoes the following description, in connc'a with the accompanying drawings, is specification, like reference characters 10 on the drawings indicating like parts in the several figures.

This invention relates to machines for shaping upper materials and is herein A hl i mechanism org to mold d or shoe p to a shoe end form the hottom or troac oduce a flange up- 'le relatively to the d dis- 0. tread molded invf r l The invento the sewing l.

from the edge of said face. A further feature consists in a novel construction and arrangement of flange forming means. In the illustrative embodiment of the invention, the shaping of the marginal portion of the upper is effected by confining the margin between advancing and closing wipers and a flange forming block of permanent contour whose edge face extends at a definite angle to the tread face of the form and engage the inner side of the upstanding margin of the upper this block being mounted on and guided by the tread face of the form for movement bv the advancing wipers a predetermined distance longitudinally of the form, which distancemay correspond to the distance it is desired to locate the upstanding flange from the edge of the form. The contour of the flange forming block will correspond to the contour of the desired flange and successive advances of the end wipers will shape the margin of the upper to the edge face of the loloclr so that the flange will upstand from the tread face at the angle determined by the angular relation of the edge face of the block to the tread face of the form.

These and other features of the invention including a novel arrangement of end embracing and clamping mechanism, and improved constructions in wiper and wiper controlling mechanisms, will be more fully pointed out in the detailed specification following and are illustrated in the accom panying drawings.

In the drawings,

As pointed out in said prior patents, the machine comprises a plurality of duplicate units built into one machine so that a plurality of shoe uppers may be in process at back and forth over the marginal portion of the same time. It will suilice to describe the present invention as applied to one of said units.

The upper shaping mechanism comprises a last or form 2, herein shown asa metal heel form of more pronounced cu A than the corresponding last; a m 1ft form embracing mold, Fins. 1, 2 and 3. backwardly into which the r rm carries the work; and heel embracing wipers, F and 5, comprising vancing d closin end members 5 and side m mners 6 t at have closing movement without advancing.

The machine is power driven, being controlled by a foot treadle 10 connected with a clutch 12 on a driving shaft 13. This shaft is geared to the cam shaft 14 which operates through a lever 15, a rod 16, and form carrier 18 to draw the fo H1 back into the mold; through a lever 20 and toggle 22 to close the moldfor clamping the upper about the side faces of the form; through certain novel connections later to be described to close the wiper controlling clutch and set the wipers to reciprocating; and through a lever 26, toggle 27, and rods 30, 32 and spring 33 to raise the form yieldingly against the wipers. These movements having been effected, the cam shaft l l comes automatically to rest While the wipers, which are driven continuously running pulley 35, are continued in reciprocation to shape the marginal portion of the upper to the margin or the tread face'of the form'2 and to form' upstanding marginal flange as later described, by repeated rubbing movements said tread face. The operator uses his judo:- ment as to the length of time during which. the work should be subjected to the action of the shaping instrumentalities and then again depresses the treadle 10. This results in the rotation of cam shaft 14 to cause opening of the wiper clutch and unjaclring of the shoe and restores all of the upper shapin instrumentalities to their starting positions, returning the inside form 2 to the position shown-in Fig. 1 preparatory to the removal of the shaped upper therefrom and the application of an unshaped upper to the form. The operating mechanism and organiza tion thus far described is like that more fully shown and described in said priorpatents and copending application, except noted, and the present invention, except as expressly stated hereinafter, is not concerned with the detailed construction thereof.

T o mold the marginal portion of the upper into an upstanding flange, the bottom face of the inside form 2 which corresponds to I the tread face of thelast or shoe, is recessed as shown in Fig. 2 to provide a slideway in whichthe base of a flange forming plate 341- is dovetailed and guided for movement longitudinally of the form and shoe end. This the plate has a permanent edge contour similar to the contour of the margin of the tread or bottom face of inside form 2 and conforming to the desired contour of the upstanding flange which is to be formed at the margin of the upper. The edge face of the plate errends at a definite angle, preferably substantially perpendicularly, to the plane of the bottom face of the form. This plate is formed with an elongated vertical slot 36 therein through which a stud 38 (Fig. 5) extends and threads into a bore 37 (Fig. 2) in the bottom face of the form. This stud in cooperation with the end wall of the slot limits and also determines the extent to which the block 362 may be moved lengthwise relatively to the edge of the form end by the advance of the end embracing wipers.

This flange forming plate, which also acts as margin holding means confining the upper against the edges of the wipers as they advance and close and restraining the marginal stoclr from doubling on itself to produce folds similarly to the deformable member of my copending application aforesaid, is maintained normally in rearwardly projected position in the slideway on form 2 with its end edge alined with or adjacent to the end edge of the form, according to adjustment, by means of the presser member 50 constituting the upper arm of'a bell crank lever fulcrumed in the form carrier 18 and having its lower and horizontal arm 52 pressed downwardly by a spring plunger (Fig. l). lVhen the carrier 18 with its inside Iorm 2 is drawn baclrwardly to draw the form back into the mold, the first advance of the wipers will move the flange plate 3 2 longitudinally of the form 2, swinging the bell crank lever 50, 52 and riding the reduced end of arm 52 up into the notch in a latch finger 6O vertically adjustable in a clamping block on spring pressed latch holding member pivotally mounted on an arm 63 which. is hung intermediate of its ends on a spindle carried ly the machine frame and held ag st an abutment at its lower end by a set screw engaging rib on the frame at its upper end. The linger 60 may be vertically adjusted to cohperate pronerly with the b ill or lr lever arm aecordi to the movementgiven said by the ad vance of the wipers, the extent of which movement may vary in different cases. This latch will engage and hold the bell crank lever until the carrier 18 is moved forwardly to unj aclr the shoe at the end of the shaping operation. The uuper end 50 of the lever cannot be swung back by the spring plunger 54, and the flange forming plate 3% will remain in the position to which it is moved by the first advance of the wipers, until the end 54 to return the flanging plate to its initial position.

Preferably, I employ a connection between the presser arm 50 of the bell crank lever and the flange forming plate which may be adj usted to vary the extent to which the plate is projected relatively to the end edge of the form at the beginning of the operation. Such a connection is shown in the set screw e -tering through a bore in the end of p e and cooperating with the presser b 56 and stud 38 adjustably to determine the initial position of the flange plate on the form and relatirely to its rear edge. By this adjustment, the flange plate may be made to project beyond the rear edge of the form to permit the upper to be pressed against it in such manner as to hold up the wings or ends of stifiener marial so that they may be molded nerly 0 er the tread face of the form ritli the upper by the wipers. There is u. tendency when the upper is clamped to the sides of a shoe end form, or when the wipers ge the upper, or the upper and end ncner when used for the stock to tip about the rear end or the form and to pull the side portions down, leaving an insufficient width of argin to bend 'n and flange and such an ao astment is advantageous w L11 molding shoe uppers and uppers prov d l with unmolded stifi'eners. Vi hen d. the end edge of melt ed stiiieners are in" the plate may be substantially alined with the sun edge he form. These and other positions of adjustment may be secured thro igi the set screw 39.

it will be evident f om the preceding description that at the start of the operation, he rear end of the edge of the flange tormplate 3% will be acent to or near the the term tread :tace at its rear exseen in Fig. 1. this position being '1 ed by previous adjustment of set accordance with the nature of had portion of the shoe end stiffener will stand .und 1e cui Jed rear end and sides of the shoe en form, and as the end wipers are adranced and closed these portions of the r k ar maintained against the edges of inc wipers will be advanced the form, progressively fiatvn the upper materials over and are bottom or tread face of the ey h ve displaced the dan ing determined by the stud hen remain in this posit of arm 52 and oescribed, and as the y achranced and re- .M m of the upper will be to the bottom race of the form and 3' of the edge of the form to the edge and r strained from downward face of the hanging plate against which edge face it will be shaped to upstand from the bottom face of the form substantially at the angle predetermined by the angular relation of said edge face to the plane of said bottom face.

When, in the operators judgment, the upper has been properly molded and flanged, the reciprocation of the wipers is discontinued and the shoe unjacked as previously described.

Preferably, the wipers are started in operation eoincidentl: with the closing of the outer mold on the form 2, and accordingly, in the illustrated machine, 1 have connected the end of the wiper-clutch controlling arm 66 with the outer mold closing toggle 22 by a second toggle 68 one of whose links carries a pin 69 which projects into a slot in the other link, the pin being engaged by the Y hooked end of one arm of a bell crank lever .70 normally held in engagement wlth sald the shapin operation to open the outer mold, the member 70 is returned to the position shown in Fig. 1.

The wiper mechanism herein shown, like the mechanism illustrated in said prior patents, comprises carrier plates 4- connected to pivot pins 7 on links 9 which extend forwardly from a cross-bar 11 on a wiper operating rod 17, the carrier plates having curved outer edges in bearing engagement with the walls of the recess in the wiper head in which the wipers are mounted. Rolls 55 on normally stationary studs 58 serve by engagement with the walls of slots 51 in the carrier plates to cause the plates to be swung inwardly and outwardly during the advancing and retracting movements imparted to them by their operating connections. The end wiper plates 5, which are constructed to operate upon the work around the curved rear end 01": the form,"are fast on the carrier plates and are jointed together to'swing with the carrier plates about an axis close to their wiping edges and subplated that the side plates 6 shall be closed inward laterally of the "form without any substantial advancing movement lennthwise of the form, and to this end the plates 6 have, dovetailed ribs slidable in guideways in the lower faces of the carrier plate, 4 and carry pins 61 which project 1lPWdlt1. y through slots 53 in the carrier plates, these pins being controlled by means to be herein after described in such manner as to restrain the plates 6 substantially from lengthwise movement while permittingthem to be swung laterally oi the form. It will be evident that in the operation of this mechanism the advancin movement of the cross bar 11 and the linlrs 9 will move the carrier plates and the end wipers 5 bodily lengthwise of the form in s ing enga ment with the side wipers G which are restrained from lengthwise movement, and that the rolls 55 in the slots will Ci -ise the carrier plates l to b swung simulta neously inward, carrying; with them the end wipers 5 and the side wipers 6.

order to malre a close joint between the members 5 and 6, the members 5 are recessed slightly on their inner edges, as shown in Fig. 4:, to provide straight slideway engagement with'the members 5, these Si ways terminating in shoulders 19 at the rear extremities of the formed edges of the membore 6 and the arrangement be at the end of the advancing L .nd clo movement of the wipers the ends of members 5 are substantially in en semen-t with the shoulders 19, thus avoid; any substantial break in the regular continuity of the formed wiper edges such as might produce an irregularity on the surface of the upper.

It isimportant to the successful operation of the upper Hanging means that the wipers at the limit of their movement shall embrace the hanging plate 34-. in substantially close relation to the edge of the plate along the sides as well as around the rear end, with due allowance of course for the thicltness of the upper materials. The construction shown provides for adjustment of the wipers to insure their location in eiiective cooperative relation to the fianginp; plate. Adjustment of the carrier plates 4 and the end wipers 5 bodily lengthwise oi the may be effected by the adjustable connec-i tion between the rod 1? and its operating means, as in former constructionssuch as shown in Patent No. 1,197fl39. A compensating adjustment of the carrier plates to ing movement of the wipers is effected by movement of the rolls 55 lengthwise of the form, these rolls having threaded studs 58 projecting through slots 59 in the cover plate and carrying clamping nuts T6. Inorder, for'example, to cause the wipers and the side win determine the proper limit of inward swing to close farther inwardly, the rolls 55 would be moved outward alone the slots 59, thus causing the carrier plates to swing about their connections with the linlrs 9 in a direction to force the wipers inwardly, such movement of the carrier plates being permitted by the provision for outward swinging movement of the linlrs 9. By reason of the manner in which the wipers are mounted and controlled, adjustment to position the different portions their edges uniform distances from the edge o1 the plate 3% usually necessit tes proportions movements oi the rod 1? of the rolls 55. It will be evident, moreover, that by relative adjustment of the rolls 55' in their slots th limits oi inwar l movement of the wipers at the opposite sides the may to some extent be vaii y.

is above stated, is desirable that at the linit of closing movement of the wipers the ends of the plates 5 be positioned close to the shoulders Of toe plates 6 in order to av id any substantial break in the regular continuity of the wiper edges. To provide for this condition, notwithstanding variations in adjustment the wipers, the pins 61 in the con ruction herein shown are connected by li' is 57 to the studs 58 of the rolls 55. lit will be evident that these links serve the purpose of the transverse guide slots 1 e-retofore provided to restrain the pins 61 from substantial movement lengthwise of the form, and each link serves additionally, unon adjusting movement of its rol 55, to ellect a correspondi coinpens adjustment of the connected side wiper plate 6. @bv1ously,

with the wiper plates 6 held against-lengthwise movement, swinn'ing movement of the carrier plates l; eii ected by adjusting the rolls 55 as above explained would slide the wiper plates 5 along the plates 6 in one direction or the other and thus vary the ultimate relation between these plates at the limit of closing movement or: the wipers. the connections 57, however, movement of the side plates 6 is ected in the proper direction comp nsate for this tendency and to insure pro continuity of the wiper edges when the wloers are closed.

In order to avoid the possibility of cistortion of the molded upper materials by tendency of the wipers to strip them from the form, it is oesirable to stop the operaion of the wipers prior to the forward reurn movement the inside form 2 and pleterably also prior to the flexing of the to ple 22 to open the outer mold and thus release the upper materials from molding pressure.
